What Is Web 2.0

While reading through my bloglines today, I found that some people who I respect don’t quite understand what Web 2.0 is all about.

While the term is overused, it seems (to me) important to understand the evolution of thought and business practice on the Internet. Tim O’Reilly does a nice job of covering the difference between Web 1.0 and 2.0:

The core competencies of Web 2.0 companies:

  • Services, not packaged software, with cost-effective scalability
  • Control over unique, hard-to-recreate data sources that get richer as more people use them
  • Trusting users as co-developers
  • Harnessing collective intelligence
  • Leveraging the long tail through customer self-service
  • Software above the level of a single device
  • Lightweight user interfaces, development models, AND business models
  • Another blogger who continually turns out impressive work relating to Web 2.0 is Nivi. Recently his post on the Dunbar Number as a Limit to Group Sizes highlighted how “After 150 people, the value of your community doesn’t grow as fast as it used to. The value may, in fact, decrease as your community grows.”

    While this only peripherally relates to black hat SEO, I believe that a careful combination of Black Hat and White Hat SEO techniques can help jumpstart peer production, communities and collective intelligence.
